There were quite a few repeat offenders on this year’s list though, as well as some notable omissions.

Filipinos will be pleased to hear their long maligned Ninoy Aquino International Airport Manila Airport, crowned worst airport three years in a row before slipping to fourth place last year, didn’t even make this year’s top 10.

However, Saudi Arabia’s Jeddah King Abdulaziz International Airport held onto its position as world’s second worst airport.

Voters were annoyed by the chaotic, crowded, unclean airport — particularly within the Hajj terminal.

“From smoking in non-smoking areas to the bathroom odor wafting out into the lounges, few people sang praises after spending time here,” said Sleeping in Airports.

Fortunately, the site said Jeddah’s days on the list are likely numbered — the new Jeddah Airport is scheduled to open mid-2016.

Nepal’s Kathmandu Tribhuvan International Airport held onto the same spot as last year — third.

Last year’s worst airport, Benazir Bhutto International Airport in Islamabad, Pakistan, slipped to ninth place, while Tashkent International Airport in Uzbekistan rose a spot to move from fifth to fourth place.

Not a single United States airport appeared in this year’s top 10, though Europe can’t say the same.

France’s Beauvais-Tille Airport slipped in to land the number 10 spot.

“Grievances from voters are detailed and far-reaching, but generally revolve around the absence of chairs, kind staff, sufficient toilets and hygienic standards,” says Sleeping in Airports of the Paris facility.

However, turning to the list airports actually do want to end up on, there were few surprises on Sleeping in Airports world’s best airports of 2015 roundup.

Singapore’s Changi International, as it has for the last two decades, held onto the top spot.

“It’s hard to know where to begin when it comes to describing the airport’s strengths,” said Sleeping in Airports.

“Perhaps, it’s the extreme efficiency experienced when moving from the airplane to the city centre? Or maybe it’s the luxurious layover indulgences, which include a fish spa, a sauna, a butterfly garden, showers and a koi pond?”

The top 10 list was dominated by Asian airports, with Seoul, Tokyo, Taipei and Hong Kong rounding out the top five.
